Definitions

  • the invention relates to a web guider for correcting lateral deviations of a running web from a target position with a rotating frame and two parallel-spaced guide rollers therein, between which the web runs and on which the web in each case by essentially 90 ° from the two Guide rollers formed guide plane is deflected, and with a position sensor monitoring the lateral course of the web behind the second guide roller in the course of the web, the output signal of which are converted into control commands for a servomotor rotating the rotating frame.
  • Web guiding devices of this type are known for example from DE 31 25 852 Cl or DE 35 35 Oll C2.
  • the invention is based on the object of enabling a web guider of this type in addition to the compensation of lateral running deviations and an exact control of the web tension in the running web.
  • a brake roller is provided in the rotating frame between the guide rollers, which is mounted with them parallel to the axis and outside of their guide level, wrapped around by the web and carried along has an actuator actuated braking device, and that a force measuring device which determines the web train in the direction of travel of the web behind the brake roller generates measured value signals which control the actuator via a controller with setpoint adjustment
  • the one determining the web train comprises
  • Force measuring device in the rotating frame along the run of the web between the brake roller and the second guide roller and with both parallel-axis, also wrapped by the web measuring roller with transducers for the forces exerted by the web due to the web tension on the measuring roller.
  • the brake roller is depending on the actuation of
  • Braking device exerted a more or less large braking force on the web wrapping around the brake roller, thereby influencing the web tension.
  • the web tension is detected on the measuring roller and in turn is used via the controller to actuate the braking device, so that there is a closed control loop for the size of the web tension.
  • the desired web train can be preselected using the setpoint adjuster in the controller. Since this web tension control only requires the wrapping of the brake roller and the measuring roller, the web tension control according to the invention takes place for the
  • Material web is very gentle on the edges and surfaces, so that even sensitive material webs can be controlled with the web guider according to the invention.
  • the arrangement of the brake roller and the measuring roller in the rotating frame itself between the two guide rollers is for the
  • the measuring roller is elastically resiliently mounted in a force measuring bearing transverse to the roller axis and in this direction the transducers absorb the force resulting from the web train on the measuring roller axis.
  • the transducers are expediently arranged strain gauges arranged on elastic bearing pieces of the measuring roller bearings.
  • the measuring roller is preferably mounted in the guide plane of the two guide rollers. It is also recommended that the measuring roller be arranged at a distance from the roller diameter of the brake roller next to the first guide roller in the course of the web and thereby the first
  • the brake device of the brake roller is formed by a pneumatically actuated disc brake and the controller has a signal converter for converting electrical control signals into pneumatic control signals.
  • FIG. 1 is a schematic side view of a web guider according to the invention
  • FIG. 3 shows the control circuit of the web guider according to FIGS. 1 and 2 used for controlling the web train in a block diagram.
  • the web guider shown in the drawing for a web generally denoted by 1 has guide rollers 2.1, 2.2 which can be freely rotated about parallel axes 3 and over whose lateral surface the web runs.
  • Guide rollers are arranged in a rotating frame 4 which is rotatably mounted on a fixed frame 5 about an imaginary axis 6 and can be rotated about this axis 6 by means of a servomotor 7.
  • the servomotor 7 is dependent on the lateral
  • the rotating frame 4 is mounted on the fixed frame 5 by means of arch guides 4 ', not shown in detail, as described in detail in DE 31 25 852 Cl, for example.
  • 2.2 of the rotating frame 4 is at least one further deflection roller each? arranged with a fixed axis of rotation. The deflection rollers 9 therefore do not take part in the adjusting movements of the rotating frame 4.
  • the output signals of the position sensor 8 are converted into control commands for the servomotor 7 of the rotating frame 4 in a known and therefore not shown and explained manner. If the position sensor 8 registers a lateral course of the web 1, the rotating frame 4 is rotated by the servomotor 7 so that the second guide roller 2.2 of the rotating frame swings somewhat in the opposite direction, so that the web between the second guide roller 2.2 and the deflection roller 9 following it returns to its target position.
  • a brake roller 11 is provided in the rotating frame 4 between the guide rollers 2.1, 2.2 with these guide rollers parallel to the axis and outside of their guide plane 10, which is wrapped around and dragged by the web.
  • the brake roller 11 has a brake device 12 actuated by an actuator, so that depending on the Brake roller 11 braking torque exerted by the braking device 12 of the web train in which the web 1 dragging the brake roller 11 can be influenced.
  • the direction of travel of the web 1 behind the brake roller 11 there is a web train determining
  • This force measuring device whose measured value signals control the actuator of the braking device 12 via a controller 13 with a setpoint setting.
  • This force measuring device consists of a in the rotating frame 4 along the course of the web 1 between the brake roller 11 and the second
  • the transducers can for example be arranged on elastic bearing pieces of the measuring roller bearings rotating strips, which is not shown in the drawing in detail.
  • the measuring roller 14 is in the guide level 10 of the two
  • the brake roller 11 is larger in diameter than the guide rollers 2.1, 2.2 and the measuring roller 14.
  • the measuring roller 14 is arranged at a distance from the roller diameter of the brake roller 11 next to the first guide roller 2.1 in the course of the web.
  • the result of this is that the first guide roller 2.1 and the brake roller 11 are wrapped around the web 1 over 180 ° each and the measuring roller 14 over 90 °.
  • the braking device 12 of the brake roller 11 can be formed by a pneumatically actuated writing brake.
  • the controller 13 has a signal converter 16 for converting electrical into pneumatic control signals.
  • the measured value signals of the measured value pickup 15 are fed to a measuring amplifier 17 with a digital display, to which a regulator unit 18 is connected, which is guided by a setpoint adjuster 19.
  • the controller unit 18 contains amplifier, summing and delay elements and works with its output on the signal converter 16, which is connected with its pneumatic part to a pneumatic supply unit 20 and with its output 21 to the pneumatically actuated disc brake 12.
